Windows: start by disabling the randomization and then
|
||||||
|
|
||||||
|
```
|
||||||
|
netsh interface ipv6 set privacy state=disabled store=active
|
||||||
|
netsh interface ipv6 set privacy state=disabled store=persistent
|
||||||
|
```
|
||||||
|
|
||||||
|
Linux: check NetworkManager or whatever you use config files
|
||||||
|
(or connection editor) or use the
|
||||||
|
kernel option directly in `/etc/sysctl.conf` or preferably
|
||||||
|
`/etc/sysctl.d/<whatever>.conf`: `net.ipv6.conf.default.use_tempaddr=0`.
|
||||||
|
|
||||||
|
The numbers you can use here are:
|
||||||
|
|
||||||
|
* 0 — IPv6 Privacy Extensions are disabled.
|
||||||
|
* 1 — IPv6 Privacy Extensions are enabled, but **SLAAC-address is
|
||||||
|
preferred.**
|
||||||
|
* 2 — IPv6 Privacy Extensions are enabled and preferred. This is usually
|
||||||
|
the default and what you should use.

### Getting IPv6
|
||||||
|
|
||||||
|
For native connectivity I only know about Finland (links in the list in
|
||||||
|
Finnish)…
|
||||||
|
|
||||||
|
* [IPv6 in Finnish consumer connections](http://ape3000.com/ipv6/)
|
||||||
|
* At the time of writing Elisa and DNA which are two of three biggest
|
||||||
|
carriers (Sonera is missing) have IPv6 in all mobile connections, DNA
|
||||||
|
has IPv6 also in broadband connections and Elisa is working on it
|
||||||
|
and Sonera has 6rd.
|
||||||
|
* [Elisa's page on enabling IPv6](http://asiakastuki.elisa.fi/ohje/541)
|
||||||
|
* [DNA's page on IPv6](https://www.dna.fi/ipv6)
|
||||||
|
* [DNA's instructions for enabling IPv6 on different devices](https://www.dna.fi/ipv6-laitteet)
|
||||||
|
|
||||||
|
…but I can suggest searching the web for `yourISP IPv6` and contacting
|
||||||
|
their customer support asking when they are going to enable IPv6.
|
||||||
|
|
||||||
|
For tunneling there are multiple services, but I am only going to mention
|
||||||
|
Teredo shortly, it's the protocol of last resolt for accessing IPv6 sites
|
||||||
|
and Windows comes with it by default. The easiest way to enable it is
|
||||||
|
probably saving the following as `something.reg` and running it:
|
||||||
|
|
||||||
|
```
|
||||||
|
Windows Registry Editor Version 5.00
|
||||||
|
|
||||||
|
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]
|
||||||
|
"AddrConfigControl"=dword:00000000
|
||||||
|
|
||||||
|
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\TCPIP\v6Transition]
|
||||||
|
"Teredo_DefaultQualified"="Enabled"
|
||||||
|
"Teredo_State"="Enterprise Client"
|
||||||
|
"Teredo_ServerName"="teredo.trex.fi"
|
||||||
|
```
|
||||||
|
|
||||||
|
Short explanation:
|
||||||
|
* Enable looking up IPv6 records even with Teredo
|
||||||
|
* Enable Teredo…
|
||||||
|
* …even if we are in domain
|
||||||
|
* use teredo.trex.fi as Teredo server, you might want to use some server
|
||||||
|
that is more [near to you](https://en.wikipedia.org/wiki/Teredo_tunneling#Servers).
|
||||||
|
|
||||||
|
Linux: install package `miredo` and edit the server in `/etc/miredo.conf`
|
||||||
|
if needed.
|
||||||
|
|
||||||
|
And then check [ipv6-test.com](http://ipv6-test.com) and it should detect
|
||||||
|
your Teredo connectivity. Some browsers don't even attempt to use it, at
|
||||||
|
least I think Google Chrome did so.

|
||||||
|
* TL;DR: depending on how you disabled IPv6 your boot might be 5
|
||||||
|
seconds lower and Microsoft discourages disabling it and they don't
|
||||||
|
test working without IPv6. Disabling IPv6 breaks e.g. HomeGroup.
